Transcript of Prezi Michael & Hasib Glacier Erosion Project

Rivers of Ice By Michael Huo The 2 General Type of Glaciers Continental Glaciers Valley Glaciers How Glaciers shape the land De la basiques. Glacial Erosion Glacial Deposition A glacier that is big... A glacier that is not as big... Covers ALOT of area around miilions of square kilometers Examples of such are Greenland and Antarctia So, as a glacier flows and crawls, it picks up rocks and dirt and grit. This process of picking up these things from the ground is called Plucking This area is often if not ALWAYS near the artic and an Now, many rocks remain stuck on to the bottom of the glacier. So as the glacier trudges on across the length and breadth of the land, the rocks get dragged along. The rocks are often very sharp and unsmooth. So the scratch and mark the land. This process is called Abrasion. Pics Bank All funds go to charity and the hungry babies Ice Age Also known as a "glacial age" So, as the glacier moves on, it gathers lots of rock and soil.And the glacier melts down due to heat, the sediment it eroded from all the land it went on, gets dropped. During a Ice age, the temperature globally drops at a steady rate. This results in the expansion of a the polar ice sheets and alpine glaciers. That's basically Glacial Deposition The last ice age was around the 20,000 years ago.This ice age shaped much of what is today of British Isles. Now for some vocab relating to Glacial Deposition Till- It's the bunch of droppings that the glacier drops when it dies. Moraine- The Theory of Ice Age Its a ridge formed at the edge of a glacier by the bunch of droppings that the glacier drops when it dies. First established in 1742 by Pierre Martel Word bank All donations and purchases go to lonely loners and hungry hungrybabies Kettle- Proven by many scientist thoughout the period between 1700s - 1870s Something that when the glacier moves, it leaves some pieces of it here and it forms a lake. - bill Theory finally proved and accepted internationally by 1870s Are you interested in seeing more frozen wonders of the natural world? - Apple Positive Feedback Negative Feedback Fun facts Glacier Gallery Are you interested in learning more about Glaciers - Hasib ChamonixIn the French Swiss Alps Siachen Glacier In the Himalayas Its a Straight Line!!!Drawn by Michael free hand!!! -Michael Random Fact Its under armed guard!Kinda Freaky!!! 10. Approximately 10 percent of the Earth is covered by glaciers; during the last Ice Age, they covered one-third of the Earth’s surface.

9. Glacier ice is the largest reservoir of fresh water on the planet, storing an estimated 75 percent of the world’s supply.

8. Glaciers are found in 47 countries.

7. A glacier can range in length from the equivalent of a football field to more than 100 miles.

6. The Antarctic ice sheet is actually a glacier and has existed for at least 40 million years. If it were to melt in its entirety, sea levels would rise 210 feet worldwide, according to the U.S. Geological Service.

5. Though it sits on the equator, Mount Kilimanjaro is glaciated.

4. On steep slopes, a glacier can be as thin as 50 feet.

3. Mountain valleys are typically “V” shaped before being taken oven by a glacier; during glaciation, the valley widens and deepens and thus becomes “U” shaped.

2. A single glacier ice crystal can grow to be as large as a baseball.

1. Alaska is estimated to have more than 100,000 glaciers. Most remain unnamed. $9.99 $9.99 Direct Quote from WWF Travel Blog $5 $500 $50 And Hasib Reza Adding a De la in front of everything doesn't make it French - Jessica There are 2 forms of glacial erosion The First (Optional) Step in Glacial Erosion Rock(y) Fail(ure)s Rocky Fails Brief Prior Knowledge Glaciers are not the best ways to erode rock.Sometimes they need a little encouragement :D Pop Quiz Which one is continental and which one is valley? X 100 X 100 :D Bylot Island Antarctica When water enters the crack between the rocks, the temperature causes the rock to freeze, causing the rocks to slowly crack. Steep Slope Indeed Defects the light from the sun and keeps less light (heat) within the planet. Decrases sea level so that less area will be and can be covered by ice sheets. THE END You see the changes, Ice Age, Iage 2, and Ice Age 3 Joking Earth has only gone though 5 major ice ages. And these are all pictures of the Mer De Glace in France Proves u got no life...- Hasib Glaciation and Landforms Erosional Landforms Depositional Landforms Landforms formed by erosion.When glaciers expand, it forms. Because of growing weight of sediment basicallyExamples of Erosional Landforms would be 'Cirques' Which are valley heads, and 'Glacial Horns', which are mountaintops which look like peaks. Formed by Glacial DepositionThe sediment that is left when a glacier moves onwards. (Glacier Retreat) 2 Examples of depositional landforms would be 'Kames' which are weirdly shapes rocks or mounds. And (Sand, Gravel) And Drumlins, which are whale-shaped hills (Glacial Ice) How glaciers affect people TODAY. Glaciers make people very cold even today!Each glacier holds water (Thank Global Warming), if not for them, there'd be a LOT more water. (Poor villages)Skiing and Snowboarding.
